Description

This is about 5hrs each of OII and Ha data from the 8in SCT. This nebula (unsurprisingly) is super dim in Ha, so the majority of the signal was OIII. I was unsure whether this one is supposed to be more greenish or blueish, however, most of the images here on A-Bin are on the blue side.

This is quite a neat nebula though, it is almost perfectly round.
